Biogas production within the bioethanol production chain: Use of co-substrates for anaerobic digestion of sugar beet vinasse

Continuous Biodegradation of Sugar Beet Distillery Stillage in an Aerobic Stirred-Tank Reactor: The Effect of Hydraulic Retention Time

“…Another method of sugar beet-based stillage management, practiced mainly by the distillery industries of India, is to use it as a component in compost production [10]. In European ethanolproducing plants, a significant role in the management of sugar beet-or sugar cane-based stillage is ascribed to the anaerobic digestion which enables energy recovery as hydrogen and methane [11][12][13]. Valuable biogas is produced during anaerobic biodegradation most often in agri-distilleries coupled with sugar factories, like for example in France -being a tycoon in ethanol production from sugar beets, but also in the Czech Republic, Romania, and Spain [11].…”

“…Valuable biogas is produced during anaerobic biodegradation most often in agri-distilleries coupled with sugar factories, like for example in France -being a tycoon in ethanol production from sugar beets, but also in the Czech Republic, Romania, and Spain [11]. However, treatment of sugar-based stillage alone during anaerobic digestion, without its additional supplementation with a carbon source or nutrients, is impossible [12]. In addition, the anaerobic fermentation process is conducted for the diluted stillage considering its high COD value and the many antimicrobial compounds it contains, including: 2,3-dimethylpyrazone, 2,2-bifuran-5-carboxylic acid, 2-nitroacetophenone, 2,2-bifulan, 2-methylhexane, methylbenzene, 2,3-dihydro-5methylfuran, p-chloroanisole, 3-pyrroline, acetic acid etc.…”

“…It can provide new clean energy jobs, prevent loss of farm jobs, and eliminate future constraints associated with the use of natural gas [15,71]. It can also provide renewable energy for strengthening the storage and preservation value chains of food systems, for improving the energetic performance of newly evolving biofuel and other renewable energy systems, as well as for facilitating the modest industrialization of rural areas at proximate distances [74,75].…”

Mathematical Modeling of the Biogas Production Process from the Distillery Spent Wash on the First Stage

“…Для вирішення проблеми співвідношення компонентів живлення використовують косубстрати (відходи тваринництва, надлишковий активний мул тощо), що дає можливість збалансувати поживні елементи, але не вирішує проблему із закисанням середовища [5][6][7].…”
